Method, device and system for preventing disassembling of global positioning system (GPS) terminal of crane

Abstract

The embodiment of the invention discloses a method, a device and a system for preventing disassembling of a global positioning system (GPS) terminal of a crane. The method comprises the following steps of: S1), acquiring first password information transmitted by the existing GPS terminal; S2) if the first password information is not acquired or the acquired first password information is not matched with second password information which is previously stored by an engine electronic control unit (ECU), entering a step S3), wherein the second password information corresponds to the designated GPS terminal, and the designated GPS terminal is the GPS terminal which is bound with the engine ECU; and S3), generating and storing a locking order in the engine ECU, so that the locking operation can be performed according to the locking order. Therefore, if the GPS terminal is privately disassembled or replaced, a password transmitted by the GPS terminal cannot be correctly read by the engine ECU, so that the vehicle is locked to punish users, and the private disassembling of the GPS terminal by the users can be effectively prevented.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a method, device and system for preventing dismantling of a GPS terminal of a crane. Background technique [0002] Cranes, especially mobile cranes, can flexibly transfer work sites and are widely used in petrochemical, metallurgy, construction and other fields. At present, many mobile cranes (hereinafter referred to as cranes) are purchased by mortgage. In this case, in order to protect the interests of banks or manufacturers, GPS (Global Satellite Positioning System) terminals are generally installed on the cranes. The GPS terminal can not only locate the crane 24 hours a day, but also has the functions of sending and receiving remote commands, communicating with various ECUs (electronic control units), and inputting and outputting. When the user (such as the purchaser or the leaser) fails to repay the mortgage loan, the authorized department such as the bank or the manufacturer can remo...

AI Technical Summary

Problems solved by technology

The inventor found in the process of realizing the present invention that the prior art cannot effectively prevent the GPS terminal from being dismantled

Although if the GPS terminal is directly removed, the relay will be normally closed and the engine will not work, but there are large loopholes in the conventional relay circuit, the user can still achieve the goal through some means: for example, directly supply power to the coil of the relay, so that the relay has power , the relay is always in the normally open state, so that the GPS terminal loses its control function and cannot control the engine to turn off; for example, if the relay is pulled out directly, the GPS terminal also loses its control function

It can be seen that the existing technology is easy to be cracked and cannot effectively prevent the GPS terminal from being dismantled
